ATTORNEY tates This invention relates to a scored, sheet blank; and moreparticularly, concerns a blank scored and slit to a predeterminedpattern for conversion into a three dimensional article suitable for anumber of purposes.

An object of this invention is to provide a sheet blank scored and slit;the blank being convertible by a folding operation which brings oppositemarginal portions thereof toward each other, into a three dimensionalarticle distinguished by parallel rows of pyramidal protuberances orprojections.

A further object of this invention is toprovide a foldable blank of thecharacter described which is convertible into articles useful forornamental, display, cushioning or insulation purposes.

Still another object of this invention is to provide a blank of thecharacter described, which is foldable along parallel lines into compactform for shipping or storage purposes, yet may be expanded to providerows of pyramidal projections with interposed cutouts, the dimensions ofthe projections and cutouts being adjustable in accordance with theextent of expansion, to produce varied ornamental effects.

Yet another object of this invention is to provide an improvedornamental device distinguished by rows of pyramidal projections and inthe form of a simulated Christmas tree, wherein the projections byreason of their relative disposition give rise to distinctive opticaleffects.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

In the drawing,

FIG. 1 is a plan view of a portion of a scored and slit blank embodyingthe invention;

FIG. 2 is a plan view of a portion of said blank in partially foldedform;

FIG. 3 is a plan View of an ornamental article derived from the blankshown in FIG. 1; and

FIG. 4 is a transverse, sectional view showing the blank in compactlyfolded, packaged form.

Referring in detail to the drawing, design-ates a fiat sheet blankembodying the invention. The same may be of cardboard, pasteboard, metalfoil faced board, plastic sheeting or other suitable material whichlends itself to scoring, slitting and folding operations. i

The blank '10 may be rectangular in shape with a front surface 11. Theblank 10 is scored on its rear surface along parallel, equally spacedlines to form parallel fold lines 12 on the front surface 11 thereof.Such fold lines 12 may also be parallel to the lateral marginal portionsof the blank, the right hand marginal portion being shown at 13 inFIG. 1. The blank 10 is thus subdivided into longitudinal portions inthe form of laterally adjacent rows indicated at 14, 15, 16, 17 and 18.

Each of the rows 14 to 18 is transversely slit at uniform intervals asat 19; the slits 19 in adjacent rows being in staggered relation, theslits in alternate rows being in transverse alignment. Thus, each pairof fold lines 12 and the intersecting pair of slits. 19 define aquadrilateral blank portion 20 which may be square in shape as indicatedin FIG. 1, or may be rectangular.

Each blank portion 20 is scored on its front surface 11 along diagonalintersecting lines 21, 22 to provide corresponding fold lines on therear surface of said blank. Score lines 21, 22 terminate at theiropposite ends at the intersection of slits 19 and fold lines 12. Theintersecatent tion of each set of score lines 21, 22 provides an apexfor a pair of laterally related triangular blank portions 23 and a pairof longitudinally related, similar triangular blank portions 24.

The blank 10 is further scored on its rear surface along longitudinallyextending parallel lines to provide parallel fold lines 25 on the frontblank surface 11; such fold lines 25 passing through the apex portionsof the triangular blank portions 23, 24- in each of the rows 14 to 18.

The scored and slit blank 10 may be converted into a three dimensionalarticle by folding the same along fold lines 12 to move the oppositemarginal portions 13 toward each other. Such folding operation willcause each of the blank portions 20 to assume a pyramidal shape due tothe folding action along the lines opposite diagonal score lines 21, 22.Furthermore, the triangular blank portions 24 will be inwardly pleatedalong fold lines 25.

As a consequence of such folding operation, folded blank 10 will exhibitrows of pyramidal protuberances or projections with inward pleats on twofaces thereof; the same being spaced in their respective rows byquadrilateral openings 26 derived from slits 19. It will be apparent,that the altitude of each pyramidal projection will be determined by theextent of the movement of the lateral blank margins 13 toward eachother, with a corresponding variation in the shape of openings 26. Thus,as the altitude of the pyramidal projections increase, the spacingbetween the laterally related apices of openings 26 decrease.

The blank 10 in its 3 dimensional form may be used as a display backingor base, having a distinctive ornamental appearance due to the pyramidalprojections. This is particularly true when the front face 11 of theblank is formed of bright metal foils. Also, such three dimensionalarticle may be used as cushioning material in packing various items offragile or semifragile nature. Furthermore, the combination ofprojections and openings make the article useful as acoustic insulationfor walls and ceilings.

The blank may also be manipulated in a particular manner to producesimulated Christmas trees, as indicated in FIG. 3. In this case, themarginal edge portions 13 of the blank are brought together as close aspossible, with the intervening folded blank portions in close surfacecontact with each other. A fastening element 27 such as a ring or stapleholds the constricted end portions 28 of the folded blank, together. Theopposite end portion of the blank is permitted to fan out, therebyproducing a tri angular shaped article in which the progressivelychanging variation in dimensions and shape of the projections andopenings in each row results in unique optical effects.

The blank 10 may be folded and compressed into compact form forpackaging, shipping and storage, as indicated in FIG. 4. The blank 10 isclosely folded along the fold lines 11 to reduce the same to a bar shapewhich may be conveniently inserted into packages of correspondingsection as indicated at 29.

As various changes might be made in the embodiments of the invention asshown, without departing from the spirit thereof, it is understood thatsuch embodiments as shown are to be deemed as illustrative and notlimiting except as set forth in the appended claims.

Having thus disclosed my invention, I claim as new and desire to protectby Letters Patent:
